Settings were persisted on the system background thread but during
first boot the device is under heavy load and persisting settings
competes with other system components using the shared background
thread. As a result persisting settings can be delayed much longer
than the expected 200ms. This can cause issues with setup wizard
being skipped/went over and its component disaabled being persisted
but the setting whether the device is provisioned not being
persisted - now if the device boots it will have no SUW but also
the home button would be missing. Generally, we need a tansactional
abstraction in the system process to peform all delayed operations
atomically.

We no longer have a null settings value - instead it is a
null object. This change adds a missing null check that is
not changed to check against the null object.

We used the system proterties as a shared memory mechanism
to propagate information to local settings caches when the
content has changed and the cache should be cleared. The
system properties are unfortunately updated asynchronously
leading to cases where clients may read stale data.
This change adds a simple int array data structure backed
by shared memory which guarantees individual values are
atomically read and updated without memory tear. Multi-
index opearations are not synchronized between each other.
The settings provider is using the new data structure to
propagate the settings generation which drives when caches
are purged.
We have a single memory array keeping the generation for
different settings tables per user. Since memory array is
not a compact data structure and the user space exceeds
the memory array size we use an in-memory map from keys
to indices in the memory array where the generation id of
a key is stored. A key is derived by the setting type in
the 4 most significant bits and the user id in the 28 least
significant bits.
The mapping from a key to an index is cleared if the user is
removed and the corresponding index in the memory arry is
reset to make it available for other users. The size of the
memory array is derived from the max user count that can be
created at the same time.

Previously many usages of UserManager.getProfiles and getEnabledProfiles
were only using ids of returned users. Given that the list of users needs
to be parceled and unparceled for Binder calls, returning array of ids
minimizes memory usage and serialization time.
A new method getProfileIds was introduced which returns an array of userIds.
Existing method calls were updated where appropriate.

It's easy for apps to throw custom Parcelables into Bundles, but
if the system tries peeking inside one of these Bundles, it triggers
a BadParcelableException. If that Bundle was passed away from the
Binder thread that delivered it into the system, we end up with a
nasty runtime restart.
This change mitigates this trouble by "defusing" any Bundles parsed by
the system server. That is, if it encounters BadParcelableException
while unpacking a Bundle, it logs and delivers an empty Bundle as
the result.
Simultaneously, to help catch the system process sticking its
fingers into Bundles that are destined for other processes, a Bundle
now tracks if it's "defusable." For example, any Intents delivered
through ActivityThread are marked as being defusable, since they've
arrived at their final destination. Any other Bundles are considered
to be "in transit" and we log if the system tries unparceling them.
Merges several Parcel boolean fields into a flags int. Add better
docs to several classes.

Make sure we commit the Global table last, so that if the
runtime was restarted before the others were written, we don't
get into an inconsistent state of migration.
Not sure if this fixes the following bug, but it's one thing
that stood out as a possibility.

from the framework when the system VR mode changes.
- Allow only a single bound VrListenerService at a time.
- Monitor allowed VrListenerService implementations from
VrManagerService and evict services as needed when packages,

- Remove previous VR functionality in NotificationListenerService.
- Add component target to Activity#setVrMode to allow

Changes to Settings.System.FONT_SCALE were not being handled by any service,
which required a device reboot for any changes to take effect. Changes to
this field by the Settings app worked as expected only because it is able to
poke ActivityManager with an updated configuration, whereas unbundled
applications cannot.
This also ensures the setting value is backed up and doesn't conflict with
a configured value from accessibility onboarding during restore.

WifiConfiguration, WifiConfigureStore and
